Rubber accelerator and its role in what?

In the rubber compound with a small amount of accelerator, can greatly promote the reaction between the rubber and vulcanizing agent (crosslinking agent), where can accelerate the speed of vulcanization reaction, shorten the vulcanization time, reduce the vulcanization reaction temperature, reduce the amount of vulcanizing agent production capacity to improve or improve the physical and mechanical properties of vulcanized rubber with the agent, known as vulcanization accelerators, referred to as accelerators. Role: accelerate the speed of vulcanization, shorten the vulcanization time, reduce the vulcanization reaction temperature, reduce the amount of vulcanizing agent, improve the physical and mechanical properties of vulcanized rubber.
